Bwindi Impenetrable Forest National Park, Uganda
I half-heartedly chased this agama around a bush for ten minutes or so trying to get a good picture. I was too tired from a six-hour trek to see the mountain gorillas to make a decent adversary for this wary lizard.

Near Bwindi Impenetrable Forest I saw several gorgeous blue-throated examples of this species from our car window. Tragically, I didn't get a photo of any of those marvelous specimens. Instead, here are mediocre photos of a couple of plainer individuals near the visitor's center at Queen Elizabeth National Park. I don't know if the dark one on the brick is a female or a male that's not wearing his colorful breeding attire.
Older literature calls this species Agama atricollis. I've also seen the genus (mis?)spelled Acanthocercus.
